Gore-step.
Krautgaze.
North Korean Black Metal.
Afroblast.
Bitch House.
Subtracto (wherein you subtract the frequency of one death metal track from some Italo, and play the results to not many shoreditch trendies).
Dog House (some people (increasingly nerds) will sample 'who let the dogs out' and use a paltry 5 seconds to base an entire genre upon. Mostly not very good).
Blinger/songwriter (ganster rappers go all James Taylor, hilarity ensues).
Blow Wave.
Kibbutzcore (radical Jewish culture goes mainstream-ish).
Mathspop (More British form of mock-quirky modern rubbish).
Punk (Modern hipsters will fail to realise there is already such a genre and accidentally re-use the name. More synths this time around).
